 Abstract
This study was conducted to understand the habitat characteristics of Psilotum nudum of Dosuncheon river and Anduck valley in Jeju Island. The total of 79 vascular plants taxa including 39 families, 58 genera, 75 species and 4 varieties were investigated in Dosuncheon river, while 59 vascular plants taxa consisting of 34 families, 50 genera, 53 species and 6 varieties were investigated in Anduck valley. When it comes to the life form, the rates of distribution of annual plants (therophytes) at the mouth of Dosuncheon river and Anduck valley were lower than those of the Korean peninsula and Jeju Island. However, the rates of distribution of chamaephytes and epiphytes were higher at the mouth of Dosuncheon river and Anduck valley. As for vegetation, epiphytes (such as Trachelospermum asiaticum var. intermedium, Trachelospermum asiaticum var. majus and Lemmaphyllum microphyllum) and adiantum plants (including Psilotum nudum, Cytomium fortunei and Rumohra aristata), which are typically easy to be dispersed in rocky zones, dominated these areas since they are vertical or horizontal joints containing wide rocky zones. The main threats to the habitats of Psilotum nudum are environmental pollution, lack of publicity, installation of various facilities such as recreational facilities, gathering for medical and horticulture purposes, vegetation succession and application of waterfront. The management of the rocky zones as habitats for Psilotum nudum is an important factor in their expansion.
